Yesterday i found this incredible app that you can do something like share location with your friends from Facebook, Contacts or email contacts.
For finding your way to the party, keeping track of family at a crowded amusement park, or getting picked up at the airport, Find My Friends is your app.
Your friends mark the spot.
Meet up with friends at an outdoor concert. Keep track of the family during a day on the ski slopes. Or see when your out-of-town guest has finally made it past baggage claim. The Find My Friends app is a great way to share your location with people who are important to you. Friends who share their locations with you appear on a map so you can quickly see where they are and what they’re up to. And since Find My Friends works with Contacts and Maps, you can do things like find the quickest route to a surprise party and avoid running into the birthday girl — all at once. Get the Find My Friends app
Good friends aren’t hard to find.
With iOS 6, you can get location-based alerts — like when friends or family members leave or arrive at a specific location. Or have them notified of your whereabouts.
Play by your rules.
With Find My Friends, you can choose when you want to be located, by whom, and for how long. It’s all up to you.
